Specilication forming pmt of Letters latcnt No. .E GQBSDRQ, dated May ll, i875; appication filed April l2, 1875.

To all whom it may concern:

Be it known that we, (Ji-matins l'iinsLnn, oi' X'Vlliamsport, in the county ot' i'iycmning and Stato ol' Pennsylvania, audJonN lli. linn- EMER, of Williamsport, in the county oi' Lycoming and State of Pennsylvania, have invented a new and usel'nl Improvement in Ice- Gutting llIaehiues; and we do here-by decla-re that the following is a l'ull and exact description ot the same, reference being .had to the accompanying drawings and to the letters of reference marked thereon.

Ihe object we have in view is the produc tion of anv ice-cutting machine that will do away with the ice-plow and handsaw usually employed in harvesting ice, and will cut sniliciently deep in one operation that, by the use ol" a splittingbar, it can he broken into the dosired blocks, and will also make a great saving in` time and cost, and our invention therein consists, first, in mount-info;l the 'l'rame ot' the machine on sleds, and the peculiar means whereby the said frame is raised oil` ot' the sleds, so as to clear the dri\v'ing.vheol, and, further, in the peculiar combination andarrangement of the several parts ol' the machine, all as more fully hereinafter set i'orih.

'lo enable others skilled in the art to make and use our invention, we proceed to describe the same in connection with the draw ings, in which- 'Figure l is a perspective view, Fig. 2 a top view, and Fig. 3 a detached sectional view, of the rear end ot' the machine, having); the side beam out away to show the guide-rods.

Similar letters denote corresponding parts in each ligure.

Arepresents the frame of a rectan gnlartbrin, consisting ofthe side beams c c and the end pieces a? c3. This frame is supported upon the sleds B C. The sled B is placed` under the end piece a2, which forms the lront part ot' the machine, and is connected lio it by a snitable ring-bolt, which allows the sled to be turned around when it is desired to turn the machine. To this sled Il is connected one or more whiflletrees for any number ot' horses. The sled C consists of two runners or separate sleds, b b, which are rigidly connected by a tiepieee, o, aud supports the rear ot' the machine. Upon the top of each sled b there are one or more rods, bl, which slide in guide-holes b2 on the underside ol" the beams a c1, near the end piece ag. To the tie-piece c are rigidly secured one or more uprights or rods, c', which are connected at their upper ends to a horizontal lc rer, D, which is pivoted at one end to end piece a, and which, when pressed down, raises the fra-me up oit' ot' the sled C, the guide-rods keeping it l'rom tilting. This lever may have any suitable means, (l, i'or holdingit in that po sition. E represents a shaft, which is journalcd in the side beams a nl, and having keyed upon it the large spiked wheel Il", which, by contact with the ice, revolves the said shaft. i is a large cog-wheel oi.l less dia-meter than he wheel F, and is also keyed on tlV e sha i't it. irl is a shaft that runs parallel with the shalt ll, and is journaled in the sidobrams c cl, and has one end projecting beyond the side beam el. To the shalt is secured a small cogavlmei, Il', which meshes with the cogavlniael. il. lwo arms, I I, are sleeved by one end to the outer end ot' the shaft I-I, outside and clear ot' the side beam al, and i'orm a frame for carrying the cutting mechanism. K is a large cog wheel keyed on the sha-it Il between the arms I l, and meshes with a small cog-wheel, L, on the shaft M, which is journaled in the arms I I near the opposite ends. 'Ihe shat't lil projects beyond one arm, I, and carries a circularsaw, N, which is secured to said shaii't in the usual way. O is a rigid band, which connects the arms I I, and keeps them the proper distance apart. I) is a leverot' any desired i'orm, which is secured to the frame I I, and is provided with a suitable handle, by which the end of the frame carrying the circular saw may bc lowered the proper distance for the saw to cut into thcice by a person walking by its side. rlhis lever may have any suitable means, c, -I'or holding the i'raine and saw above the ice when desired. lhere may be one or more seats on the niaehine t'or the driver and a person to raise and lower the saw.

By this machine there is no need of lirst marking' the ice with a plow, and the saw can he made large enough to out from six to eight inches deep, or even more, itl required.

Having thus described our machine, what we claim as our invention, and desire to sccure by Letters Patent, is
